Get onto them tomorrow and tell them you have a "Stuck Profile" of 500kbps. They need to get it unstuck. Get politely insistent if they tell you it is in 10-day training, as in this case that is irrelevant.
If they say profiles take up to 5 days to rise, that is also irrelevant here, as large jumps are supposed to happen within hours, and you can't get much larger than the one you expect.
They should be able to see those speed test results, but have them ready to refer to.
